get rid of the last LOOKUP_RCU dependencies in link_path_walk() New helper: terminate_walk(). An error has happened during pathname resolution and we either drop nd->path or terminate RCU, depending the mode we had been in. After that, nd is essentially empty. Switch link_path_walk() to using that for cleanup. Now the top-level logics in link_path_walk() is back to sanity. RCU dependencies are in the lower-level functions.
